Black-headed Trogon

Trogons are primitive birds found in many of the world’s tropical areas. Ornithologists are uncertain about to which birds they are most closely related. Surprisingly, genetic research indicates a relatively close affinity to African mousebirds (Collar 2018).

Black-headed Trogons range from southeastern Mexico to northern Costa Rica. Unlike most trogons, this one is found in open habitats—this bird flew between trees and shrubs in a suburban area near the Hotel de Campo on 11 July 2017.

Trogons nest in arboreal termite colonies. Here the make nesting cavities, which contain a long, curved tunnel that ends in a circular nesting chamber. They eat fruit and arthropods, such as caterpillars and large insects (Riehl 2012).
